Re: Impala queries through impala JDBC is running with empty user

Interestingly, though many people in this thread are complaining of the same issue, no one has posted an error message that shows the correct syntax as outlined by the manual in the link from @Lars Volker.

Specifically, the manual shows the syntax for the connection string with a username (and no password) should be using AuthMech=2:

jdbc:impala://node1.example.com:21050;AuthMech=2;UID=impala

At least for me, this "resolved" the issue because now I am trying to debug a connection timeout. So I guess that is progress :/

Re: Impala queries through impala JDBC is running with empty user

It seems like this thread still has no resolution. I was inclined to give the benefit of the doubt to Cloudera and assume this was a DBeaver issue but it seems other people using straight Java cannot get a working connection string either.

It would be great if we could get a cloudera employee to have another look at this thread. In particular, Dbeaver is an outstanding DB client and I was using it with great success before I started using authentication. It is a real shame to have lost it.

Can anyone successfully use the connection string from the manual (username, no password)?
